Protein Synthesis Review

Which of the following is a difference between DNA and RNA?

• DNA is single stranded, RNA is double stranded
• DNA has thymine, RNA has uracil
• There are 3 types of DNA, there is only 1 type of RNA

What is protein synthesis?

• Reading instructions in DNA to make proteins

• Reading instructions in proteins to make DNA

• The replication of DNA

• The replication of proteins

What are the main two steps of protein synthesis

• Translation and transformation

• Transformation and transcription

• Transcription and transformation

• Transcription and translation

What happens during transcription?

• DNA is made into amino acids
• DNA is made into mRNA
• DNA is made into a protein

mRNA is?

• messenger RNA that takes the instructions from the DNA to the ribosome

• messenger RNA that takes the instructions from the RNA to the protein

• matching RNA that binds DNA with the correct RNA

• matching RNA that binds RNA with proteins

Where does transcription take place?

• Nucleus
• Ribosome
• tRNA

What happens during translation?

• mRNA matches up with tRNA to form a protein
• tRNA matches up with DNA to make a protein
• DNA is copied into mRNA

Where does translation take place?

• Nucleus
• Ribosome
• Mitochondria

What would the mRNA sequence be for the following DNA code; ATG?

• TAC
• UAA
• UAC

What enzyme is responsible for making mRNA from DNA?

• DNA polymerase
• RNA ligase
• RNA polymerase
